   ### Modules
   Angular apps are modular. They consist of many files each dedicated to a purpose.
-  ES5 JavaScript doesn't have modules, but we don't want to pollute the global namespace.
   
-  So we'll surround the code in a simple IIFE ("Immediately Invoked Function Expression").
-  It receives our `app` 'namespace' object as argument. 
-  We call our IIFE with `window.app` if it exists - and if it doesn't we 
-  initialize it as an empty object.
+  ES5 JavaScript doesn't have a native module system.
+  There are several popular 3rd party module systems we could use.
+  Instead, for simplicity and to avoid picking favorites,
+  we'll create a single global namespace for our application.
+  
+  We'll call it `app` and we'll add all of our code artifacts to this one global object.
+  
+  We don't want to pollute the global namespace with anything else.
+  So within each file we surround the code in an IIFE ("Immediately Invoked Function Expression").

-  Most application files *export* one thing into our faux-pas 'namespace', such as a component.
+  We pass the global `app` namespace object into the IIFE, 
+  taking care to initialize it with an empty object if it doesn't yet exist.
+  
+  Most application files *export* one thing by adding that thing to the `app` namespace.
   Our `app.component.js` file exports the `AppComponent`.
